Smoke detectors work according to the light scattering principle caused by
smoke particles present in the air. The smoke detector has the automatic gain
control function; a microcontroller calculates reading compensation to keep
constant sensitivity and corrects any level increase due to dust depositing
into the analysis cell. Smoke detectors shall be installed in places protected
against draughts which may divert the flow of combustion particles and in
places where the common activities performed do not cause gas material
fires.

Low profile heat detector, complete with self-learning circuit and short-circuit
isolator.
• Heat detectors monitor the temperature values in the area where they are
installed.
• A microcontroller analyses and compares the signal received from a NTC
type temperature detector and activates the alarm if the read temperature
exceeds 58°C.
• Power supply: 20Vdc (modulated voltage between -15% and + 10%)
• Average absorption at rest: 250 mA@20Vdc
• Absorption at alarm: 2mA@20Vdc
• Static alarm threshold: 58°
• Two-colour led: red alarm - green regular operation
• Relative humidity max: 93%
• Working temperature: 0 ÷ 50°C
• Weight: 70 g
• Dimensions: ø 90 x 40 (H) mm
• Compliant with EN54 Standards, part 5 class A1S, certification number:
1293-CPD-0084.
